1.4 UPPER LED READOUT
The default display of this readout is the temperature sensed at Probe 2. In a Boiler, Probe 2 will be
inserted into the outlet area and can control the outlet temperature. In a Water Heater, Probe 2 will
be inserted into the appropriate area of the storage tank to provide effective temperature response
for the heat source (this may not be at the top of the tank).
By pressing and releasing the
button once, the Upper LED will display the actual
temperature sensed at Probe 3 (Optional Temperature Probe. Used for Outdoor Reset on
Boilers).
By pressing and releasing the
button twice, the Upper LED will display the difference
between the actual temperature sensed at Probe 2 and the temperature sensed at Probe 1 (if
used).
To return to the default in the Upper LED readout, wait 15 seconds after the
button is
pressed and released twice.
1.5 LOWER LED READOUT
The default display of this readout is the temperature sensed at Probe 1. In a Boiler, Probe 1 will be
inserted into the return piping of the boiler heating loop. In a Water Heater, Probe 1 (if used) will
be inserted into upper area of the storage tank.
By pressing and releasing the
button once, the Lower LED display will show the Time of
Day. Press again to return to default display.
1.6 TO SET THE CURRENT TIME AND DAY (MILITARY TIME)

displayed in the Lower LED readout.
2. Pushing the
or button alternates the LED readouts between the following:
“Hur” (hour) in the Upper readout and its value in the lower readout
“Min” (minute) in the Upper readout, its value in the Lower readout
“dAY” (day) in the Upper readout, its value in the Lower readout
3. To adjust a value, press the
button and the value in the Lower LED will start flashing.
Change the value by pressing the
or buttons. When correct, press .
4. To exit push
